THis driver operates the controller. This module also includes a slave mode, which will be submitted later on. Any feedback would be appreciated. v2 -> v1: - run check patch in strict mode. - use linux crc. - define regs in constant offset without base. - remove debug prints. - no declerations for local functions. v1: initial version Signed-off-by: Tali Perry --- .../devicetree/bindings/i2c/i2c-npcm7xx.txt | 27 ++++++++++++++++++++++ MAINTAINERS | 8 +++++++ 2 files changed, 35 insertions(+) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-npcm7xx.txt diff --git a/Documentation/devicetree/bindings/i2c/i2c-npcm7xx.txt b/Documentation/devicetree/bindings/i2c/i2c-npcm7xx.txt new file mode 100644 index 000000000000..e2ee45d7a41e --- /dev/null +++ b/Documentation/devicetree/bindings/i2c/i2c-npcm7xx.txt @@ -0,0 +1,27 @@ +Nuvoton NPCM7XX I2C bus + +The NPCM750x includes sixteen I2C busses + +Required properties: +- compatible : must be "nuvoton,npcm750-i2c-bus" +- reg : Offset and length of the register set for the device. +- interrupts : Contain the I2C interrupt with flags for falling edge. +- clocks : phandle of I2C reference clock. + +Optional: +- bus-frequency : Contain the I2C bus frequency, + the default I2C bus frequency is 100000. +- pinctrl-0 : must be <&smbX_pins>, X is module number + (on NPCM7XX it's 0 to 15) +- pinctrl-names : should be set to "default" +Example: + + i2c0: i2c-bus@80000 { + compatible = "nuvoton,npcm750-i2c-bus"; + reg = <0x80000 0x1000>; + clocks = <&clk NPCM7XX_CLK_APB2>; + bus-frequency = <100000>; + interrupts = ; + pinctrl-names = "default"; + pinctrl-0 = <&smb0_pins>; + }; diff --git a/MAINTAINERS b/MAINTAINERS index 192d7f73fd01..13bac916d21d 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -1244,6 +1244,14 @@ F: drivers/i2c/busses/i2c-aspeed.c F: Documentation/devicetree/bindings/interrupt-controller/aspeed,ast2400-i2c-ic.txt F: Documentation/devicetree/bindings/i2c/i2c-aspeed.txt +ARM/NUVOTON I2C DRIVER +M: Tali Perry +L: linux-i2c@vger.kernel.org +L: openbmc@lists.ozlabs.org (moderated for non-subscribers) +S: Maintained +F: drivers/i2c/busses/i2c-npcm7xx.c +F: Documentation/devicetree/bindings/i2c/i2c-npcm7xx.txt + ARM/ASPEED MACHINE SUPPORT M: Joel Stanley R: Andrew Jeffery -- 2.14.1
